This paper reviews the recent findings in the non-linear stress-strain behavior and damage processes of ceramic matrix composites. The material systems examined include Nicalon fiber reinforced calcium alumino silicate (CAS), silicon carbide (SiC) and silicon nitride (Si{sub 3}N{sub 4}). The fiber geometric systems are: unidirectional, cross-ply, two dimensional woven fabric and three-dimensional braided preforms. Analytical modeling focuses on the initiation and evolution of damage, degradation of elastic properties and modes of failure. Correlations of theory and experiments have been made.
